JERSEY HEEL oov'anme "MACHINQBV Application fi led November 2], 1927,.se ia1j1vof2sa5se,,1 i l This invention relates to machines foroperating upon shoe heels, particularly grooved'heels, andis hereinillustrated as embodied in a machine for facilitating the covering ofheels with sheet material.

0 material, an operation Whichhas heretofore- One important ob ect of heinvention'is to provide an efficient machine for accurately" and rapidlysecuring to a heel block the meeting edge portions of a piece of heelcovering been performed by hand. A more specific object is to'provide amachine for tucking into the groove of a grooved 'heelblock the meetingedge portions of the covering mater al. V I V y Withthese objectsinView, the invention comprises a machine in which are combined meansforpositioning-a heel-blockand means for securing in succession to theblock the meeting edge portions of thegheel cover.

In theillustrated embodiment of the inven tion, the'machine isprovidedwith a single means arranged to secure the cover to a heelblock, as by tucking the covering magroove in the block, and isoperative upon the two meeting 1I 1'Sl1CCSS1OIl.

a In this connection, invention is also to be recognized in the combinaton with a tucking blade Which is 'verythin, and, therefore, liabletolbe'deformed -if subjected to much bending force, of meansforpositioning a grooved v heel block 'withits groove in the plane of saidblade, and means for effecting relative movement of the block andtheblade thinner than would otherwise be practicable:

' a This is very advantageous with some kinds of 7 heel coveringmaterial, inasmuch as, it pery mits tucking the' material into thegroove "without compressing the material beyon'd'the terial into agroove inthe block, the preferred form of means for accomplishing thisfunc-- tion consisting of a' reciprocabletucking blade which is movableinto and out'of the edge portions of the heel cover in the plane of theblade, to tuck heel cover ing material into the'groove. Bymechanitucking blade is withdrawn the said' material can expand to fillthegro'ove, so that a very 'secure and neat attachment is obtained;
